Following the accident, Nabezadeh followed the celebrity to the gates of her children’s school to try and get further details from the 45-year-old.

McCartney, Nabezadeh said, took his number and her husband, Alasdhair Willis, called the next day to give their insurance details.

Nabezadeh told The Sun: “I didn’t even know who she was until my passengers told me. She’s very wealthy. She shouldn’t have done this to me. It’s very unfair.”

A spokesman for McCartney said the designer had never been in this “type of incident before” and was sorry it had occurred.

He added: “Although she and the taxi driver did not swap full details, Ms McCartney thought that an insurance claim could be made from the licence plate number she was happy to provide, and knew the taxi driver had a full note of. She thought she had done the right thing.

“When the driver, with two passengers, started filming her after the incident, she felt intimidated particularly when she realised they had followed her to the kids school, still filming her.

“She accepts liability for the incident and is very apologetic for any issues that have arisen from this incident.”
